CHANGES IN THE ANTIOXIDATIVE ACTIVITIES OF BEAN PRODUCTS AND INTESTINAL MICROFLORA IN THE MODEL OF THE GASTROINTESTINAL TRACT “ IN VITRO ”

The aim of the research project was to determine the effect of the human intestinal microflora on changes in the active, natural biological compounds which occur in products obtained from bean seeds. In addition, the authors ascertained the “in vitro” microflora survivability in the applied model of the gastrointestinal tract during the digestion of these products. During the “in vitro” digestion process, the highest antioxidative activity was determined in the case of the instant flour and extruded products (ca. 46 mg Tx/g) at a relatively low total content of phenol compounds – 5.94 and 3.35 mg/g, respectively. The products subjected to the digestion process stimulated the growth of intestinal microorganisms and, at the stage of the “large intestine”, their numbers ranged from 10⁸ to 10⁹ cfu/mL in the case of all the identified microorganisms.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN.
